A large and diverse set of manufactured materials are in powdered form at one stage or another. No matter what the material is, from cement to metered dose inhaler ingredients, product performance is related to particle size distribution. “The strength of concrete is related to the fineness of the cement powder used, but the danger with very fine grades is excessive heating on setting,” says…, ASTM Committee E29 Next Meeting:, Oct. 6-7, 2014, October Committee Week, New Orleans, La., Technical Contact:, Alan F.

In many testing laboratories, it can be necessary to qualify a new test method, instrument or lab itself with respect to one or more performance characteristics. One such key characteristic is bias, or mutual agreement of average test results run on the same material. A proposed ASTM standard will aid in the determination of bias equivalency. ASTM WK37659 , Guide for Testing for Bias Equivalency…
